nice Piece. The first thing I saw was the wirement. It was complete replaced and at a first look the Cords with Plug and weights are missing. With the aggreement from Albert I upload a Pic from his site. So you have a lot work to do. I knew a guy who will sell 1 or 2 Untersatz A (but original wired but need spare Parts too). If you interested you can send me a PM.
